Which of the following are dimensionally consistent? (Choose all that apply.)(a) a=v / t+xv2 / 2(b) x=3vt(c) xa2=x2v / t4(d) x=v

Answer:

A Type I error could occur if the test shows that the proportion is above 90%, while in reality, the actual proportion is 90%.

Step-by-step explanation:

Machines in a factory produce circular washers that meet a specific diameter.

The quality control manager routinely assesses samples of washers to ensure that more than 90% conform to the specified diameter.

Let p represent the proportion of washers that meet the specified diameter

Thus, Null hypothesis: p = 90%

Alternative Hypothesis: p > 90%

Now, a Type I error indicates the probability of rejecting the null hypothesis while it is actually true or, in simple terms, the likelihood of incorrectly rejecting a valid hypothesis.

Thus, based on our question, a Type I error would declare that the test convincingly indicates the proportion is over 90%, while in truth, it remains 90%.

It is established that

A correlation between two variables, x and y, demonstrates a direct variation if it can be written in the format or

For this question, we have

the point lies on the direct variation line

therefore

Determine the constant of proportionality k

-------> substitute ------>

The equation is

Keep in mind that

If a point is located on the direct variation line

then

the point has to fulfill the direct variation equation

we will now validate each point

case A) point

Insert the values of x and y into the direct variation equation

-------> is valid

thus

the point lies on the direct variation line

case B) point

Insert the values of x and y into the direct variation equation

-------> is valid

thus

the point lies on the direct variation line

case C) point

Insert the values of x and y into the direct variation equation

-------> is not valid

thus

the point does not lie on the direct variation line

case D) point

Insert the values of x and y into the direct variation equation

-------> is valid

thus

the point lies on the direct variation line

case E) point

Insert the values of x and y into the direct variation equation

-------> is not valid

thus

the point does not lie on the direct variation line

case F) point

Insert the values of x and y into the direct variation equation

-------> is valid

thus

the point lies on the direct variation line

ultimately

the solution is
